Ah, YES!! Tylenol can damage your/baby's liver if too much is used. It all depends on how much is taken and for how long. There are clear instructions for dosage on the bottle. I would follow them to be safe.

While the nurse practioner had me freaked about tyenol the Pharmacist(forte is drugs)said extra strength is even fine.Any medication you are worried about a Pharmacist can answer your questions right away with 100% correctness.
